Børsesjø - Sedimentanalyser og rapportering av overvåkingsresultater 1990
(NIVA-rapport;2617, Research report, 1991)Vannkvaliteten i Børsesjø er sterkt påvirket av partikler og plantenæringsstoffer fra landbruksaktiviteter i innsjøens nedbørfelt. Dette resulterer i grumsete vann i flomperioder og kraftig oppblomstring av alger i ... -
Calculating expected effects of treatment effectivity and river flow rates on the contribution of WWTP effluent to the ARG load of a receiving river
(Peer reviewed; Journal article, 2021)Concentrations of genetic markers for antibiotic resistance genes (ARGs) were measured in the effluents of three Norwegian wastewater treatment plants (WWTPs) and in a receiving river upstream and downstream of the discharge ... -
Can benthic foraminifera serve as proxies for changes in benthic macrofaunal community structure? Implications for the definition of reference conditions
(Journal article; Peer reviewed, 2018)Benthic macrofauna is one of the most widely used biological groups to assess the ecological status of marine systems. Lately, attention has been paid to similar use of benthic foraminifera. In this study, distribution ... -
Can current moisture responses predict soil CO2 efflux under altered precipitation regimes? A synthesis of manipulation experiments
(Journal article; Peer reviewed, 2014)As a key component of the carbon cycle, soil CO2 efflux (SCE) is being increasingly studied to improve our mechanistic understanding of this important carbon flux. Predicting ecosystem responses to climate change often ... -
Can improved nutrition for Atlantic salmon in freshwater increase fish robustness, survival and growth after seawater transfer?
(Peer reviewed; Journal article, 2021)The loss of fish in the seawater (SW) phase of Atlantic salmon farming is high, and a major proportion of this loss occurs in the period just after SW transfer. In the current study, we hypothesize that improvements made ... -
Can multitrophic interactions and ocean warming influence large-scale kelp recovery?
(Journal article; Peer reviewed, 2019)Ongoing changes along the northeastern Atlantic coastline provide an opportunity to explore the influence of climate change and multitrophic interactions on the recovery of kelp. Here, vast areas of sea urchin‐dominated ... -
Can plastic related chemicals be indicators of plastic ingestion in an Arctic seabird?
(Peer reviewed; Journal article, 2024)For decades, the northern fulmar (Fulmarus glacialis) has been found to ingest and accumulate high loads of plastic due to its feeding ecology and digestive tract morphology. Plastic ingestion can lead to both physical and ... -
